Scheme related to 7 Watt Audio Amplifier with IC TDA2003:

This is a class AB 6-10W audio power amplifier circuit which built using a TDA2002 or TDA2003 power amplifier IC module. These are replacements for the original LM383 which is no longer available. It is easy to build and has a minimum of external components. The module has ...

This is a 18W audio amplifier circuit based on power IC HA13118. The supply voltage required for this circuit is 8 - 18V DC, at least 1 to 2 Amps. Maximum output power will only be obtained with a power supply of 18V at greater than 2 A, ...

This is 20 watt power audio amplifier which use IC LM1875 as main component. This circuit is simple and very easy to built. For stereo channel, you need to build 2 same circuit which will amplify each channel (right and left channel). The LM1875 is a monolithic power ...

Here is a Hi-Fi power audio amplifier circuit, built with a power IC TDA2050. This circuit will produce a power output up to 32watt. With good sound quality, high power and very low distortion feature, this circuit will be very suitable for simple and cheap audio systems. TDA2050 ...

This is 68W power audio amplifier circuit which built based on single IC LM3886 from National Semiconductor. A LM3886 used for single channel operation. Dual polarity / split / symmetrical power supply used to operate this amplifier circuit. The LM3886 is a high-performance audio power amplifier capable of ...
